引用ジャーナル : Nat Struct Mol Biol / 年 : 2024タイトル : Structural basis of human U5 snRNP late biogenesis and recycling.著者 : Daria Riabov Bassat / Supapat Visanpattanasin / Matthias K Vorländer / Laura Fin / Alexander W Phillips / Clemens Plaschka / 要旨 : Pre-mRNA splicing by the spliceosome requires the biogenesis and recycling of its small nuclear ribonucleoprotein (snRNP) complexes, which are consumed in each round of splicing. The human U5 snRNP ... Pre-mRNA splicing by the spliceosome requires the biogenesis and recycling of its small nuclear ribonucleoprotein (snRNP) complexes, which are consumed in each round of splicing. The human U5 snRNP is the ~1 MDa 'heart' of the spliceosome and is recycled through an unknown mechanism involving major architectural rearrangements and the dedicated chaperones CD2BP2 and TSSC4. Late steps in U5 snRNP biogenesis similarly involve these chaperones. Here we report cryo-electron microscopy structures of four human U5 snRNP-CD2BP2-TSSC4 complexes, revealing how a series of molecular events primes the U5 snRNP to generate the ~2 MDa U4/U6.U5 tri-snRNP, the largest building block of the spliceosome. 履歴 登録 2023年8月17日 - ヘッダ(付随情報) 公開 2024年4月17日 - マップ公開 2024年4月17日 - 更新 2024年5月29日 - 現状 2024年5月29日 処理サイト : PDBe / 状態 : 公開
